aDolus FACT - Malware Detection vs YAYA - Yet Another Yara Automaton: Side-by-Side Comparison (2026)

aDolus FACT - Malware Detection

Mid-market and enterprise teams managing software supply chains will get the most from aDolus FACT because it consolidates multiple antivirus engines and YARA rules into a single malware detection workflow, catching threats that isolated scanners miss. The tool maps component relationships to identify hidden infection paths, and covers NIST GV.SC (supply chain risk management) and DE.AE (adverse event analysis) with actual depth rather than surface-level compliance. Skip this if you need post-infection response or threat hunting; FACT stops at detection and doesn't help you understand how malware moved through your network after the fact.

YAYA - Yet Another Yara Automaton

Threat hunters and incident responders who need to operationalize Yara rules without writing automation scripts should use YAYA; it pulls open-source rule sets, deduplicates them, and runs scans automatically, saving weeks of manual curation work that most teams skip entirely. The GitHub community has validated the approach with 302 stars and active maintenance, which matters because stale Yara tooling becomes useless fast. This is free software, so there's no vendor lock-in, but also no support contract if your scan performance tanks on a 10TB dataset or your rules conflict in production.
